I did notice that in the 09 one it only says to connect CG and TC (no TS) to read the codes. You might want to give that a try, just in case the three connections was a misprint in the 07 manual.

Yes, that's what I did -- just CG and TC. According to the '07 manual, connecting all three is done to read test code mode.

The P/S light went on again tonight on the way home as soon as I started the car. I stopped and checked the codes immediately -- 91 and 92 again. This got me to thinking... there are three ECU codes for connection with the ECM with DTCs unlike the others: U0073, U0105, and U0121. It also states "When two or more DTCs starting with [U] are output simultaneously, inspect the connectors and wire harness of each ECU."

I accidentally did some slight damage to the plastic white connector on A21 when I was installing cruise control recently, but I didn't think much of it. I wonder if this might be related. I'm going to double-check it.

UPDATE: I pulled A21, inspected it, pushed locking mechanism back in fully, and reattached. So far no trouble. I am going to have the dealer read the code with the intelligent tester when I take it in for the 25,000 mile service this coming week. I'll let you all know what they say -- hopefully it may help someone else with the same problem searching the boards down the line. Thanks again for all the help so far!
